Shell Irus C
High performance HFT-type fire-resistant hydraulic fluid
Shell Irus Fluid C is an advanced water-glycol fire resistant hydraulic fluid containing powerful additives to enhance its anti-wear, anti-corrosion and anti-oxidation properties. The water content is approximately 40% by weight.
Main Applications
Irus Fluid C is particularly suitable for demanding hydraulic applications where there is a high fire risk, such as those found in the Metal and Mining industries.
In order to reduce the water evaporation Irus C, as for all the ISO HFC type of fluids, should be used below 55°C with a suggested max temperature of 45°C.
